Keep your new Kuat bike rack safe by locking that bad boy to the hitch using the Locking Hitch Pin. This pin works with a 1-1/4-inch rack in a 2-inch receiver and is compatible with a range of Kuat racks. The Locking Hitch Pin is available in either a 1-1/4 or 2in version. Two keys are included so you can keep one with your car keys and stash the other at home.
